Data erased overnight!

I have been using this app almost daily for the last 4 years. It was great and I had no complaints at all, until... All of my data was erased overnight! I tried restoring from backup but it wouldnt let me do it. Emailed the developer and heard nothing from them. Very disappointed that I paid for the app and have been relying on it so much with my records. Guess you just cant trust technology 100%... Now Im moving on to another app and hopefully it would be better than this.
